DLC Series

The DLC Series Compact High Resolution Sensor is based on All Sensors’ CoBeam2 TM Technology. This reduces package stress susceptibility, resulting in improved overall long term stability. This technology breakthrough advances the state of the art for piezoresistive pressure sensors beyond what has been achieved for low pressure sensing using silicon based
strain technology.

The low supply voltage allows for integration of the sensors into a wide range of process control and measurement systems, as well as direct connection to I2C serial communications channels. The DLC series offers 16 bit digital resolution. The digital interface options ease integration of the sensors into a wide range of process control and measurement systems, allowing direct connection to serial
communications channels. For battery-powered systems, the sensors can enter very low-power modes between readings to minimize load on the power supply.

These calibrated and compensated sensors provide accurate, stable output over a wide temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air and dry gases.

Specification notes

NOTE 1: The Span is the algebraic difference between full scale decimal counts and the offset decimal counts. The full scale pressure is the maximum positive calibrated pressure.

NOTE 2: Total Error Band consists of offset and span temperature and calibration errors, linearity, and pressure hysteresis errors, offset warm-up shift, offset position sensitivity, and long term offset drift errors.

NOTE 3: Parameter is characterized and not 100% tested.

NOTE 4: Data update time is exclusive of communications, from command received to end of busy status. This can be observed as EOC pin low-state duration.

NOTE 5: Average current can be estimated as: ICCIdle + ((tDU / Reading Interval) * ICCActive.) Refer to Figure 2 for active and idle conditions of the sensor (the active state is while EOC pin is low).

NOTE 6: The sensor is calibrated with a 3.3V supply; however, an internal regulator allows a supply voltage of 1.68V to 3.6V to be used without affecting the overall specifications. This allows direct operation from a battery supply.
